Let every ride be Epic!

Rimpact Original MTB tyre inserts give you the confidence to take on any trail, rail every corner, and send the big jumps without fear of damaging your rims or getting a flat.

How is this possible? Rimpact is inserted into the inner core of the tyre, providing a cushioning layer that absorbs trail impacts to protect the rim and stabilise the tyre sidewall minimising tyre roll and burping. This allows you to run lower tyre pressures, permitting the tyre to efficiently conform to trail obstacles increasing tyre traction, while dampening trail vibrations that lead to forearm pump, while reducing the ability for objects to penetrate the tyre causing a flat.

Rimpact inserts are an engineered mountain bike tyre insert manufactured from high density, closed cell and cross-linked polyethylene foam used in the aerospace industry. The result is a lightweight, highly impact absorbent foam insert for tubeless mountain bike tyres that provide the following benefits:

- Dissipates force away from the rim
- Controls rebound increasing traction
- Stabilises sidewalls – reduced tyre roll/burping
- Makes Lower pressures viable
- Dramatically reduces trail chatter

The kit comes with two un-blockable presta valves made of CNC'd aluminium with horizontal air ports. This design ensures the valve will not block even if the insert shifts. They work with sealant injectors, have removable cores and can be run in a regular tubeless setup.

Suitable for rims with an inner diameter of 23mm - 35mm and tyre widths 2.3 - 2.6 inch tyres. It is possible to use the insert with narrower or wider tyre but it will increase the difficulty of fitting. Do not purchase if your rims are outside of this spec.

Weight: approx. 95g per insert for 29, and 90g approx for 27.5

Contents Per Pack:
- 2x Rimpact Original MTB Tyre Inserts
- 2x 44mm Rimpact Unblockable Valves
- 2x Sets of Stickers

To install Rimpact Inserts you will have to convert the the tyre to a tubeless system if you have not already done so.  We recommend Stans NoTubes sealant and rim tape.

- Dissipates force away from the rim
- Controlled rebound increases traction
- Stabilises sidewall for reduced tyre roll
- Makes lower tyre pressures viable
- Does not absorb sealant

Easy fit

Got the 27.5 original, easy to install on first attempt using previous tyre (Maxxis Dissector 2.5wt). Damping and tyre stability improved, like the idea of being able to run flat in an emergency - rides okayish as low as 10psi!

Hi Sam,

Thanks for the fantastic review of our Rimpact products.

Just a comment on running the tyre at 10psi, we have noticed a significant tradeoff of speed vs grip when running a tyre at such a low psi. Our guys that race downhill and gravity enduro events are running low to mid 20's psi on the front and mid to high 20's on the rear. Doing so keeps the speed up and helps to absorb some of the hits before the insert needs to do its job. Agree, the run-flat is a great feature of the inserts.

Cheers,
